UNITED sTATEs PATENT oEFlcE THERMOMETER WITH SPRAY Robert Leopold,Philadelphia, Y. and Anthony Breau, Yeadon, Pa., assignors toThermoscopic Spray Sales, a partnership Application June 4, 1948, SerialNo. 31,093 'Y 7 claims. (ci. 'z3- 343) This invention relates to sprayheads and more particularly to a spray head having a temperatureindicator incorporated therein.

The testing of the temperature of water from spray heads by the reactionof the temperature on the skin is wholly unreliable as the estimate ofwater temperature varies greatly among different people. Seriousdiiculties can arise, particularly in spray apparatus used for bathinginfants where resort is had merely Ato skin reaction temperature testson the part of the mother. Difculties also arise in other uses of sprayheads, such as in beauty parlors, for shampooing and the like. Y

It is the principal object of the present invention, therefore, toprovide a spray head in which the temperature of the fluid beingdelivered in the form of a spray is indicated to the( user so that theproper adjustment may be made of the water supply to bring thetemperature to the desiredA level.

It is a further object of the present invention to .provide a spray headwhich may be readily constructed from transparent synthetic resinousplastic material and having a temperature indicator combined therewith.

It is a further object of the present invention to provide a spray headhaving athermometer combined therewith and in which the thermometer ismounted in a manner so as to be protected from shocks and the like.

It is a further object of the present invention .to provide a spray headconstructed in an improved manner so as to be light in weight whileretaining adequate strength and rigidity.

Other objects and advantageous features of the invention will beapparent from the specification and claims. v

The nature and characteristic features of the invention will be morereadily understood from the following description, taken in connectionwith the accompanying drawings forming part hereof, in which:

Figure l is a top plan view of a spray head in accordance with thepresent invention;

Fig. 2 is an underneath plan view thereof;

Fig. 3 is a central sectional view taken approximately on the line 3-3of Fig. 1; and

Fig. e is a transverse sectional view taken approximately on the line'3-4 of Fig. l.

It should, of course, be understood that the description and drawingsherein are illustrative merely, and that various modifications andchanges may be made in the structure'dis-closed zvithout departing fromthe spirit of the invenion.

Like numerals refer tolike parts throughout the several views.

Referring now more particularly to the drawings, the spray head, inaccordance with the present invention, preferably includes a body por:tion I0 having a nipple II formed thereon or connected thereto for theattachment of a flexible hose I2 through which the liquid forthe sprayis supplied. The body portion I0 is preferably dished or hood shaped andhas, on the exterior thereof, a iiattened' portion I3 for the mountingof the nipple I2 by suitable cement. The body portion luis preferably oftransparent synthetic .resinous material, acrylic resins being suitablefor this purpose. The body portion has an opening I4 in communicationwith the central opening I5in the nipple II. The interior of the bodyportion I0 above the lower rim portion theref` of is preferably providedwith acircular groove or slot having a well portion It parallel to thecentral longitudinal axisof the body portion Ill and the nipple Il, anda wall portion I'I per--4 pendicular to the wallportion I6 andaccordingly normal ,to the, central longitudinal axis. The groove orslot defined by the Walls I6 and lII is adapted for the reception of'thecomplemental peripheral edge I8 of a spray plate I9. The vspray plate I9may be dished oppositely to the body portionIII) and is provided with apluralityfof sprayv openingsI 20 for the delivery of the liquid in sprayform. The spray plate Ilis preferablyof the same material as the bodyportion I9 and secured in position in the slot defined by the walls Itand Il by suitable cement. A liquid chamber 2| is thus provided in theinterior of the body portion IU and insidethve spray plate I9.

In the linterior chamber 2|, a mounting block 22 is provided, for thesupport'of a thermometer 23. The block 22 is preferably secured to theinterior of the body portion Il) and may also, if desired, be secured tothe spray plate I9 at the time of assembly.

The fthermometer 23l is preferably of the ex-i pansible liquid typevwith a bulb 24 from which a straight stem portion 25 extends. Thestraight stem portion 25 preferably extends through an opening 26 in themounting block 22, the portion of the stem at the block 22 beingenclosed within a short tubular sleeve 2l of resilient materialresistant to the temperatures encountered. One suitable material for thesleeve 21 is synthetic rubber of the type sold under the name ofNeoprene.

'I'he thermometer 23 has, extending from the straight stem portion 25, acurved indicating stem portion 28 which is in substantial aline- 3i mentwith the slot defined by the Walls i6 and IT. The stem portion 28, atits terminal end, has an expansion chamber 28a to accommodate excessivetemperatures. The bulb 24 of the thermometer 23 is preferably disposedsubstantially in .alinement with the .central opening l in the nipple5H.

The body portion IIJ, on the exterior thereof contiguous to theindicating portion 21 of the stem of the thermometer, is preferablyprovided with suitable temperature indicia l'29, l preferably in therange from 50 F. to 160 F., and if desired, special temperature levelsmaybe marked.

The temperature of the waterdelivered'through the hose l2 to thechamberfZl effective on the thermometer 24 may be readily observed andthe supply adjusted to provide the desiredftemperature level of thewater delivered through the spray openings 20.

The likelihood of breakage is reduced andlow thermalconductividsyis'provicledby Athe use of acrylic resinous material.
